217.7002 - Policy
DoD policy is to exchange, rather than replace, eligible nonexcess property whenever exchange promotes economical and efficient program accomplishment. Exchange policy, authority, and applicability are governed by—
(a) The Federal Property Management Regulations issued by the Administrator of the General Services Administration; and
(b) DoD Manual 4140.01, Volume 9, DoD Supply Chain Materiel Management Procedures: Materiel Programs.

217.7003 - Purchase request
Ensure that the requiring activity provides all of the following in support of the purchase request—
(a) A certification that the property is eligible for exchange and complies with all conditions and limitations of DoD Manual 4140.01, Volume 9, DoD Supply Chain Materiel Management Procedures: Materiel Programs.
(b) A written determination of economic advantage indicating—
(1) The anticipated economic advantage to the Government from use of the exchange authority;
(2) That exchange allowances shall be applied toward, or in partial payment of, the items to be acquired; and
(3) That, if required, the exchange property has been rendered safe or innocuous or has been demilitarized;
(c) All applicable approvals for the exchange; and
(d) A description of the property available for exchange (e.g., nomenclature, location, serial number, estimated travel value).

217.7004 - Solicitation and award
(a) Solicitations shall include a request for offerors to state prices—
(1) For the new items being acquired without any exchange; and
(2) For the new items with the exchange (trade-in allowance) for the exchange property listed.
(b) The contracting officer is not obligated to award on an exchange basis. If the lowest evaluated offer is an offer for the new items without any exchange, the contracting officer may award on that basis and forgo the exchange.
(c) Exchanges may be made only with the successful offeror. When the successful offer includes an exchange, award one contract for both the acquisition of the new property and the trade-in of the exchange property. The only exception is when the items must be acquired against a mandatory Federal supply schedule contract, in which case, award a separate contract for the exchange.

217.7005 - Solicitation provision
Use the provision at 252.217-7002 , Offering Property for Exchange, when offering nonexcess personal property for exchange. Allow a minimum of 14 calendar days for the inspection period in paragraph (b) of the clause if the exchange property is in the contiguous United States. Allow at least 21 calendar days outside the contiguous United States.
